Hematology analysis is an important step in medical diagnoses, often determining the treatment that a patient will receive. With a patient’s life on the line, it is vital that these analyses are accurate to the highest degree possible. Researchers at HORIBA Medical, a worldwide supplier of medical diagnostic equipment, turned to simulation to develop new methods for optimizing the accuracy of their hematology analysis devices. The resulting technique is currently used in some of their best-selling equipment.

In a recent blog post, we discussed the growth in 3D metal printing and its impact on manufacturing. Today, we shift our focus from the industry as a whole to a particular technique that has been instrumental in the production of metal prototypes, as well as plastic, ceramic, and glass materials — even coffee. Selective laser sintering has taken the world of 3D printing by storm.

Coil heat exchangers are simple and easy to manufacture. Here, we consider an axially wound coil of copper carrying hot water that heats air inside of a circular duct. Since the geometry is almost invariant about the centerline, the model is solved in the 2D axisymmetric plane. Additional expressions are added to compute the temperature drop between turns of the coil, which greatly simplifies the modeling.

In the design of many structures, a particular area of concern is exposure to seismic and wind-induced vibrations. Viscoelastic structural dampers have been implemented into structural layouts as a means to limit the strain and decrease the risk of failure in building components due to such excitations.

Safe and cost-effective drilling is a major issue in the oil and gas industry. In addition to the common prospecting risk, the borehole itself provides uncertainties that are not desired, but unavoidable. Today, we would like to show how numerical simulations can help here. The goal is to predict the stability of an open-hole multilateral well for deciding if the well will need expensive mechanical stabilization — or not.

The chemical industry is considerably important to economies around the world, playing a critical role in processes ranging from the production of clean drinking water to the manufacture of pharmaceutical products. Chemical engineers are faced with the challenge of ensuring profitability in a rapidly growing and evolving market. Packed bed reactors are one of the most common reactors used in the chemical industry due to their high conversion rate per catalyst weight compared to other catalytic reactors.

Diabetes is an incurable global killer: the World Health Organization estimates 350 million diabetics worldwide, with an average annual fatality rate close to 1%. Fortunately, modern medical science enables diabetics to manage their glucose levels and intake, so many countries have seen greatly reduced danger of the disease. Many diabetics must track their glucose levels throughout the day, requiring an accurate method for measuring the concentration of glucose in blood. For modern sensor designs, the method of choice is electrochemistry.
